Mark Szamatulski has been the co-owner and operator of Maltose Express since 1990. He and his wife Tess have written the books Clone Brews and Beer Captured. These books each give homebrew recipes for commercial beers and help the home beer maker to brew great beers on the first attempt. Mark and Tess have written the Style column for Brew Your Own magazine, where they are on the Editorial Board, and have contributed many articles to the publication. Their beers have been awarded many medals in homebrew contests, and have had their beers put on the tap of a local brewery. Time.com has filmed their store for its website, and they were the subject of a Discovery Channel segment on homebrewing which was featured on the show “How Stuff Is Made.”
